So, we were out of state visiting relatives during Christmas week, then
returned home to find still more relatives camping out at our place. They
stayed for another week -- O joy :-(
When with drooping eyes we stumbled in from the airport to celebrate the
third (yes, third) Christmas gift opening, I found a handful of radio tube
boxes in my stocking, jumbled around with mints, chocolates, and whatnot.
"Cute -- garage sale crap," I thought, and put them aside.
Today I got around to looking at the handful and discovered six NIB National
NL-840 Nixie tubes, each including a base and matching IC chip.
I guess my brother-in-law's challenge is to make a Nixie clock. (He is an
actual "rocket scientist" -- a grey-haired guidance expert from Florida.)
Also in the stocking, and perhaps these are unrelated stuffers, 10 NIB
Miller coils: eight 3-10 mh (#9060), one 19khz (#1361) and one 38 khz
(#1362).
Anyway, the draggers are drawn. I need an NL-840-based Nixie clock plan, and
I need it now!
The ICs included with the Nixie tubes have the following markings:
DM/SN7441AN
NS8840N 122
